Coronary Stent Strut Fractures: Classification, Prevalence and Clinical Associations
2021
Introduction. The frequency, characteristics and clinical implications of Strut fractures (SFs) remain incompletely understood. Methods and results. A total of 185 (160 patients) newer-generation drug-eluting stents (DES) were imaged. SFs were found in 21 DES (11.4%) and were classified in four patterns: one single stacked strut (41%)
The effect of cement fixation on initial micromotion of the femoral component in condylar knee replacement
1992
Four fresh, cadaveric specimens were fitted with total knee replacements and mounted on a knee joint loading and measuring rig. Femoral component micromotion in the sagittal plane was measured with a transducer during flexion and extension of the specimen. Various condylar designs were used without and with cement. Movement followed a characteristic curve pattern and was less with cement fixation particularly for bone of low trabecular strength as determined by bone sample tests for stiffness. Cement fixation appears to be superior to cementless fixation.
Postoperative Patient Education in Physiotherapy after Hip Arthroplasty : Patients' Perspective
2017
Objective The objective of the present study was to explore postoperative patient education in physiotherapy from total hip arthroplasty (THA) patients' perspectives, which has been a little‐studied area of research. The usefulness of rehabilitation protocols after THA has been debated over the years, and there are no clear guidelines for physiotherapy after THA Methods The data for the present qualitative study were collected from nine patients with THA by using individual interviews at the hospital after surgery. The interviews were audio‐recorded and analysed by using a phenomenographic method Results Four different categories of postoperative patient education in physiotherapy after hip…
Differences in Accuracy and Radiation Dose in Placement of Iliosacral Screws: Comparison between 3D and 2D Fluoroscopy
2022
Percutaneous iliosacral screw fixation is a widely accepted method of stabilizing the posterior pelvic ring. Recently developed tools such as 3D-navigated fluoroscopy and computed navigation seem to prevent a surgeon from conducting screw misplacement. The study aimed to comparatively assess the introduction of sacroiliac screw placement using 2D and 3D fluoroscopy in terms of accuracy and radiation exposure. Iliosacral screws were introduced in 37 patients using 2D (group N1) and in 36 patients using 3D fluoroscopy (group N2) techniques. Overall, 61 and 56 screws were introduced in groups N1 and N2, respectively. Screw placement accuracy was assessed using postoperative computed tomography…
Comparison of Postoperative Coronal Leg Alignment in Customized Individually Made and Conventional Total Knee Arthroplasty
2021
Neutral coronal leg alignment is known to be important for postoperative outcome in total knee arthroplasty (TKA). Customized individually made implants (CIM) instrumented with patient-specific cutting guides are an innovation aiming to increase the precision and reliability of implant positioning and reconstruction of leg alignment. We aimed to compare reconstruction of the hip–knee–ankle angle (HKA) of the novel CIM system iTotal™ CR G2 (ConforMIS Inc.) to a matched cohort of the off-the-shelf (OTS) knee replacement system Vanguard™ CR (Zimmer Biomet). Retrospective analysis of postoperative coronal full-leg weight-bearing radiographs of 562 TKA (283 CIM TKA, 279 OTS TKA) was conducted. V…
Gender, identity and representation in video games : an elective discourse-oriented course for Finnish EFL upper secondary school students
2015
Suomen koulujen opetussuunnitelmat pyrkivät toteuttamaan ja edistämään tasa-arvoa, mutta tasa-arvon toteutuminen koulujen arjessa vaatii vielä työtä. Samaan aikaan videopeleistä on tullut suosittu harrastus nuorten ja aikuisten keskuudessa, mutta sekä pelit että peleihin liittyvä keskustelu ovat tasa-arvon suhteen jälkijunassa. Pelaaminen ei ole enää yksinomaan nuorten poikien harrastus. Monet oppijat sukupuoleen katsomatta pelaavat erilaisia pelejä ja osallistuvat pelejä koskevaan keskusteluun. Tämän pro gradu -tutkielman tavoitteena on tuottaa lukio-opetukseen tarkoitettu kurssimateriaalipaketti, jonka avulla kuka tahansa opettaja pystyy lähestymään naisten representaatiota videopeleissä …

2019
Speciālo nozaru angļu valoda ir pieprasīta dažādu jomu speciālistu vidū, jo sniedz iespēju apgūt profesionālo angļu valodu. Šī pētījums mērķis bija noteikt militārās angļu valodas apguvēju individuālās valodas vajadzības un izveidot mācību materiālus, kas veicinātu viņu mutvārdu saziņu. Mācību materiāli tika izstrādāti, izmantojot uz uzdevumiem balstītu metodoloģiju, kas nodrošina valodas apguvi, izmantojot jēgpilnus uzdevumus, atbilstošus komunikatīvus vingrinājumus, lai veicināti valodas funkciju apguvi, kas nepieciešamas, lai attīstītu valodu tās lietojumam reālās situācijās. Pētījuma dati tika iegūti, izmantojot anketas, nodarbību novērošanu, un progresa testus, kas tika rūpīgi analizēt…
Theoretical Models of Industrial Espionage
2012
Dada la importancia del espionaje industrial en la realidad económica, el objetivo de la presente tesis es analizar teóricamente el comportamiento de las empresas a la hora de obtener información de sus competidores, para poder comprenderlo mejor y ver cuáles pueden ser sus consecuencias, ya que, aunque el espionaje industrial es una práctica muy extendida, pocos trabajos teóricos han tratado de analizarlo. Más concretamente, nuestro objetivo es analizar teóricamente el impacto del espionaje industrial sobre el comportamiento estratégico de las empresas en un contexto de disuasión de la entrada usando las herramientas propias de la Teoría de Juegos. En los modelos de la presente tesis se co…
Joint local quantization and linear cooperation in spectrum sensing for cognitive radio networks
2014
—In designing cognitive radio networks (CRNs), protecting the license holders from harmful interference while maintaining acceptable quality-of-service (QoS) levels for the secondary users is a challenge effectively mitigated by cooperative spectrum sensing schemes. In this paper, cooperative spectrum sensing in CRNs is studied as a three-phase process composed of local sensing, reporting, and decision/data fusion. Then, a significant tradeoff in designing the reporting phase, i.e., the effect of the number of bits used in local sensing quantization on the overall sensing performance is identified and formulated. In addition, a novel approach is proposed to jointly optimize the linear soft-…
Mellommenneskelige aspekter i operasjonsteamet -operasjonssykepleieres opplevelser : kvalitative intervju med operasjonssykepleiere om opp- levelser …
2014
Masteroppgave i spesialsykepleie – Universitetet i Agder 2014 Background: Experiences from practice in surgical units led us to question what makes teamwork effective and elegant, and also reflect upon the causes of situations where the teamwork is less than optimal and team members become frustrated. Purpose and research question: We based our research design on some of the relational factors defined in Reeves et al. (2010) conceptual framework for interprofessional teamwork. This was done to explore how surgical nurses experience these factors in relation to cooperation in surgical teams. We chose the following research question: How do surgical nurses experience the relational factors of…
